No, but it is extremely annoying in most cases, and ends up getting the
client firewalled, (in my book anyway), if the results are not cached.
Persistent SAV probes for every mail, even when minutes apart, are a prime
example. If, BIG IF, however, he does use it to feed a whitelist as he
later mentioned, that would not be a problem|annoyance.

I will be honest though, even after Peter pointed out the plus point if
implemented correctly, I still cannot see an overall benefit from this
method. The concept would be simple to circumvent if it became generally
deployed.
